We work in the field of experimental soft matter physics including biophysics. Soft materials used in cosmetic industries are investigated to explore their underlying structures and corresponding viscoelastic properties. These structures are altered by tuning the electrostatic interaction among the self-assembled aggregates in amphiphilic systems. In turn, the materials show interesting physical properties which are important for industrial applications. We also work in the field of membrane biophysics to develop model systems to investigate the interaction of macromolecules (e.g. protein, DNA etc.) with model cellular membranes. We are now embarking on to develop devices for bio-medical applications using nano-technology. Different x-ray scattering (x-ray diffraction, x-ray reflectivity, grazing incidence x-ray diffraction etc.) and microscopy techniques are used at in-house and international synchrotron facilities to study the structures and properties of such soft materials and bio-systems.

Sajal Kumar Ghosh did his Ph. D from Raman Research Institute, Bangalore, India. There after he joined as a post-doctoral scientist in the Institute for X-ray Physics, University of Goettingen, Germany. Then he moved to the University of California-San Diego (UCSD), California, USA to work as a post-doctoral scholar. Sajal has research experience in the field of soft matter physics including bio-physics. He has presented his research works in many international conferences in India, Germany, Italy, France, Spain and USA. His present interests are in i) tuning viscoelastic properties of soft materials by altering the self-assembled aggregates, ii) developing simple model systems to facilitate physical and chemical studies of bio-systems, iii) developing devices which are useful for drug delivery, non-destructive molecule counter etc. using nanotechnologies.
